# What is the percent by mass of NaHCO_3 in a solution containing 50 g NaHCO_3 dissolved in 750 mL of water?

6.25%

#### Explanation:

A solution is a homogeneous mixture consisting of a solute and solvent. The solution is typically defined by the amount of solute dissolved into an amount of 'solution'. So calculating the percent component in the solution would be ...

Wt% of component = (("Weight" "of" "Component")/("Weight""of""Solution"))xx100%

where (Solute Wt + Solvent Wt) = Solution Wt.

For this problem ...

Wt% "NaHCO_3 = ((50 g NaHCO_3)/((50g + 750g)Solution))xx100% = 6.25% by weight
